L2786 Rev. M
Note:
Normal ventilation shall be suspended for the duration of the maneuver. The maneuver will be aborted if a patient effort
is detected and the message bar will indicate a message stating that patient effort was detected.
Controls
Tidal Volume (Volume)
This is the volume of gas delivered to the patient during the maneuver.
Range: 0.10 to 2.50 L (Adult)
25 to 500 mL (Pediatric)
Resolution: 0.01 L (Adult)
1 mL (Pediatric)
Default: 0.25 L (Adult)
25 mL (Pediatric)
Peak Flow
Sets the Peak Flow used for the maneuver.
Note: A square wave flow pattern is used for the maneuver.
Range: 0.5 to 5.0 LPM
Resolution: 0.1 LPM
Default: 1.0 LPM
Maneuver PEEP (PEEP)
The Maneuver PEEP determines the baseline pressure at which the maneuver begins.
Note: The Maneuver PEEP can be set independent of the PEEP used during normal
ventilation.
Range: 0 to 50 cmH

PEEP Equilibration Time (PEEP T
eq
)
The PEEP Equilibration Time determines the amount of time allowed for equilibration of the
airway pressure before slow flow commences. Upon activation of the maneuver the ventilator
will set PEEP to the Maneuver PEEP level for the PEEP Equilibration Time prior to beginning
the slow flow maneuver.
Range: 0.0 to 30.0 seconds
Resolution: 0.1 second
Default: 1.0 second
Sensitivity
The preset Sensitivity establishes the level below the peak airway pressure that the pressure
must drop to abort the P
flex
maneuver.
Note: The Pflex maneuver will be terminated if a leak greater than 100% is present.
Range: 0.1 to 5.0 cmH
